The unit's selftest is meant to qualify the rate of discharge of the internal battery in direct relation to the percentage of attached load during testing. When discharging, the battery voltage must remain within the designated Load percentage algorithm pre-set in to the unit's EEPROM, to pass the selftest.
Traditional FDM falls far short of the expected results and cannot meet the requirements. Therefore, the fault diagnosis model based on WOA-LSTM algorithm proposed in the study can improve the safety of the power battery of new energy battery vehicles and reduce the probability of safety accidents during the driving process of new energy vehicles.
Hi, This means your UPS failed its battery self test. The batteries are likely bad and require replacement. This is what would be expected anywhere from 2-5 +years old depending on the battery usage, environment, etc. If this UPS is new and/or in warranty, you'll want to contact technical support.
In order to monitor the health status and service life of the battery, the team of Samanta designed a battery safety fault diagnosis model based on artificial neural network and support vector machine (Samanta et al. 2021). We compared the model with other models. The results showed that the fault detection accuracy of the model reached 87.6%.
During the internal failure process of a battery, various gases are prone to be generated, especially during TR. As the temperature gradually rises, the intense reaction processes occur, producing a variety of toxic, flammable, and explosive gases.
In the comparison of the safety performance and maintenance cost of the power battery after using three models, this model could improve the safety performance of the battery by 90.1% and reduce the maintenance cost of the battery to the original 20.3%.
